To all whom it may concern i '1 Specification of Letters Patent.

a citizen of .the United States,v residing, at

F-ulda, in the county of Murray: andState of Minnesota, have invented anew and useful Tire-Fastening Means,

lowing is a specification.-

One object of the present invention -to provide novel means. forholding; the longitudinal edges of a :tire nterlocked with a With theforegoing and other objects in view, which will appear as -thedescription proceeds, the invention resides in-the combi-- nation andarrangement of parts and in the of which the foldetails ofconstructionhereinafter described" and claimed, it being understoodthatchanges in'the precise embodiment of invention herein disclosed canbe made within the scope of what is claimed without departing fromthespirit of theinvention.

In the accompanying draWings,.Figure 1 shows in sectional sideelevation, a portion of a wheel equipped with the device constitutingthe subject-matter of this application; Fig. 2is a transverse sectionofthe structure shown in Fig. 1, the cutting plane being passed along theline A'B of Fig. 1; Fig. 3 is a perspective of one of the tire sections;Fig. 4 is a perspective of the tire-retaining member.

In the drawings there is shown a rim, de-

. noted generally by the numeral 1, the same comprising a felly 2 and afelly band 3, the felly band 3 having clencher ribs 4. The tire ispreferably fashioned from resilient metal and comprises'a plurality oftrough sections 5 having at their ends, projecting tongues 6.Considering each section 5 as a unit, the tongues which are upon theopposite ends of. each section alternate with each othercircumferentially of the tire. When one section 5 is assembled withanother like section, the tongues of the adjacent sections willalternate with each other Owing to this construction,the desired'play ofthe meeting ends of the sectionsb will be afforded, and at the sametime,the tire will be of great strengthat the meeting ends of the sections.The sections 5 are equipped. at

engage with the clencher ribs of th'e'felly band 3. i

The invention further includes a; pair of tire-engaging membersS whichmay be sev-f ered rings, restingf uponthe felly jband 3 i the membersShaving inclinedouter faces 9 adapted to engage the sections5to'holdtheflanges 7 engaged 'witl1 tlie 'clencher ribs 4:1

The inner faces of the tire engagingi mombers 8 51am; toward the'medianplane oft-he wheel and toward the hub of the wheelfas indicated at 10. qi

The invention further aplural- I ity of tire-retaining' members 1 1', ofwhich tire-retaining members there may be any number. The tire-retaininginember H' is preferably in theform of a plate provided at its edgeswith diverging flanges 12 adapted to engage the faces 10 of thetire-engaging members 8;

' Extended through the tire-retaining member 11, and if desired, rigidlyconnected therewith, is a bolt 14 which passes through the felly band 3andthrough the felly 2, there being a nut 15 upon the bolt 14, which nutengages the intrados of the felly 2. Pins 17 or other projections extendfrom the folly band 8, the pins 17 engaging in slots 16 formed in thebody portion of the tire-retaining member and extended through theflanges 12 thereof.

' Presupposing that the parts are positioned as shown in Fig. 2 it willbe observed that by loosening the nut 15, the bolt 14: may be movedtoward the periphery of the tire, carrying with it the tire-retainingmember 11, the hold of the tire-retaining member to permit the clencherflanges 7 of any desired section 5 to be disengaged from the clencherribs 1 of the fe'lly band 3, whereupon any desiredsection 5 may bedisengaged from the adjoining sections, to permit the renewal of adefective section. The manner in which the tongues 6 of the sectionsinterengage with 1 each other has been pointed out hereinbefore. Theprojections l7serve to prevent the tire-engaging members 8 from movingtoo far in the direction of the median plane of the tire when thetirearetaining member 11 isloosened. In addition to the foregoingfunction, the projections 17 engage the tireretaining member when thesameis seated on the telly band 3, and serve to prevent thetire-retaining member 11 from moving circumferentially of the wheel.

As will be understood readily, when the nut 16 is tightened, thefianges12 of the tire-retaining member llwill engage with the faces 10 of thetire-engaging members 8, forcing the members 8 laterally until theirfaces 9 engage with the sections 5 and into engagement with force theflanges 7 the ribs 4. V

Recalling that the sections 5 are fashioned from spring metal, it isobvious that the a wheel will possess the desired resiliency, and

i at the same time, the possibility of a, punc- I Copies of thil patentmay be obtained for a tire'having its edgesinterlockedwith the ribs andlocated between the ribs and the hands; a tire retaining =stri p bearingagainst the inner edges of the bands to hold the latter in contact withthe tire; and a securing element uniting the strip with the rim; thestrip having elongatedtransverse openings and the rim having pins whichengage in the openings to hold the strip against creeping, the stripbeing removable from the pins and the pins lying hetweenthe securingel'e mer t-and, ribs .andinthe path of the bands, thereby to limitthemovement of the latter toward the median plane of theflrimwhen thestrip is removed from thepins. v
